Methods of test for ancillary components for masonry - Part 5: Determination of tensile and compressive load capacity and load displacement characteristics of wall ties (couplet test)

This European Standard specifies the couplet method for determining the tensile and compressive load capacity and load displacement characteristics of wall ties embedded in mortar joints. The test is intended for ties used for connecting together two leaves of masonry and for the mortar bedded end of ties for connecting masonry leaves to other structures.

Prüfverfahren für Ergänzunsbauteile für Mauerwerk - Teil 5: Bestimmung der Zug- und Drucktragfähigkeit sowie der steifigkeit von Mauerankern (steinpaar-Prüfung)

Diese Europäische Norm legt das Steinpaar-Verfahren zur Bestimmung der Zug- und Drucktragfähigkeit sowie der Lastverschiebungseigenschaften von in Mörtelfugen eingebetteten Mauerankern fest. Die Prüfung ist vorgesehen für Anker, die zur Verbindung von zwei Mauerwerksschalen verwendet werden, und für das in Mörtel eingebettete Ende von Ankern zur Verbindung von Mauerwerksschalen mit anderen Konstruktionen.

Méthodes d'essai pour composants auxiliarires de maçonnerie - Partie 5: Détermination de la capacité de charge de traction et de compression et de la rigidité d'attaches de murs (essai sur paire)

La présente Norme européenne décrit une méthode d'essai permettant de déterminer la charge admissible à la traction et à la compression et les caractéristiques effort-déformation des attaches murales ancrées dans des joints de mortier. L'essai est conçu pour des attaches prévues pour relier deux parois de maçonnerie ou deux murs à angles droits. Il s'applique également à des attaches utilisées pour relier les bords de murs de remplissage aux cadres ou aux ossatures qui les entourent.

Metode preskušanja dodatnih komponent zidovine - 5. del: Ugotavljanje natezne in tlačne nosilnosti ter lastnosti sila-pomik zidnih veznih stremen (preskus z dvema zidakoma)

Ta evropski standard določa metodo z dvema zidakoma za ugotavljanje natezne in tlačne nosilnosti ter lastnosti sila-pomik zidnih veznih stremen v malti med dvema zidakoma. Preskus je namenjen za vezna stremena, ki se uporabljajo za povezavo dveh slojev zidovine, in za konce veznih stremen v malti za povezavo slojev zidovine z drugimi strukturami.

Foreword
This document (EN 846-5:2012) has been prepared by Technical Committee CEN/TC 125 “Masonry”,
the secretariat of which is held by BSI.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest February 2013, and conflicting national standards shall
be withdrawn at the latest by February 2013.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such
patent rights.
This document supersedes EN 846-5:2000.
The principal changes in this document form the previous edition relate to the tie position, the number
of ties to be tested, the location of the clamp during testing and the treatment of slope and movement
tolerant ties. Ties are to now be placed at the minimum declared embedment length rather than a
length calculated from the tie length and design cavity width. Ten ties are tested in tension and ten in
compression. In the compression tests the ties are loaded over an extended cavity, or alternatively
provision is made for evaluating the cavity section by calculation. Where ties are designed to tolerate
either an induced slope or movement then prior to test they are cycled fifty times through the slope or
movement for which they have been designed.
According to the CEN/CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of
Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain,
Sweden, Switzerland, Turkey and the United Kingdom.

This European Standard specifies the couplet method for determining the tensile and compressive
load capacity and load displacement characteristics of wall ties embedded in mortar joints. The test is

tests or for making the couplet specimens shall be taken from the same consignment.
The conditioning of masonry units shall be as specified.
Record the method of conditioning the masonry units prior to laying. Measure the moisture content by
mass of autoclaved aerated concrete and calcium silicate units in accordance with EN 772-10.
Record the age of non-autoclaved concrete units at the time of testing the masonry specimens.
